Crap is a pretty strong word. pkg dependencies aren't that straight forward, 
especially not cross platform, and pkg-config is cross platform. 

As we have changed to CMake, I have been looking for a substitutes, but not 
found any. Maybee the new --find-package option to the latest CMake will do 
the trick, which by the way is called "running cmake in pkg-confiog mode".

But I have been reluctant trying this because it uses the latest CMake release 
which is not available on mody platforms. Also it gives a much smaller list of 
dolfin dependencies than the pkg-config call, which I guess you call a feature 
;)
